Title: Parking system for two-wheelers
Inventor: ZELTWANGER ULRICH
IPC: B62H3/02
Filed: 1993-05-04
Abstract: The invention relates to the proper setting and parking of two-wheelers in accordance with type without bringing about damage, whether the damage be due to distinctive structural features of the parking system for two-wheelers or whether it be caused by other two-wheelers, and without resulting in the risk of injury for people using it. In order to make this possible, the proposal is for a parking system for two-wheelers for parking at least one two-wheeler, which system, for each parking cell, has two guides which protrude out of an approximately horizontally lying portion of a supporting frame, define the parking cell laterally and between which the two-wheeler is placed when parked and which are arranged above the centre of gravity of the two-wheeler to be parked and below parts projecting laterally from said two-wheeler, and to which barriers are attached which block those surfaces, which are adjacent to the guides, on their side facing away from the parking two-wheeler, and to the horizontally lying frame portion, and are determined by the width of the two-wheeler, at least partially against the direction in which parking takes place.

Title: Ultrasonic tomography of cross=section esp. of turbine shaft and blade disc
Inventor: SCHREINER THOMAS DIPL ING
IPC: G01N29/07
Filed: 1994-05-16
Abstract: An ultrasonic tomogram for a cross-section of a body is produced from a grid of image points (20) overlapping the cross-section. Several series of echo transit time spectra are recorded. In each series transit time spectra are recorded as the amplitude of an ultrasonic original (3) echo as a function of its transit time for a given incidence angle (5) and divergence (6). In each series a partial tomogram is produced on the grid, whereby values are assigned to each image point based on distribution of reflectors on the grid derived from the transit time spectra. The final tomogram is produced by assigning a standardised value of the partial tomogram values to each image point.
Patent DE-4423861-A1 (DE)
Title: Fastening device for interchangeable cutting inserts provided with a cylindrical pin
Inventor: GROESCHEL HOLGER
IPC: B23B27/16
Filed: 1994-05-25
Abstract: The true cutting-material costs of high-speed cutting materials such as PCD, CBN or high-speed ceramic are continually increasing due to the applied technological manufacturing processes, so that only the regrinding of the cutting inserts permits efficient use of these cutting materials. The known cutting inserts, especially with brazed-in cutting corners, have no shaped element which is suitable for facilitating automated manipulation for positioning and clamping. In the novel fastening device, the cutting insert is provided with a cylindrical pin (1) and shaped elements (2) in order to permit accurate positioning for cost-effective regrinding (even in the case of small batch quantities) and anti-rotation fixing for absorbing the cutting forces. Thus the same datum plane (centre position and diameter of the pin, and size and position of the shaped elements) is present for each regrinding operation (including the measurements for quality assurance). Cutting inserts with different inscribed-circle diameters (i.e. up to ten regrinds) can be used on the same holder (3); only the insert carrier (4) has to be changed in accordance with the inscribed-circle diameter of the cutting insert. Square, rhombic, triangular and round cutting inserts are used. <IMAGE>
